My husband (27) hasn't been feeling well for 2 weeks. He developed a rash on his chest, neck, back and shoulders. He recently found a lump on the back of his head a couple inches behind his right ear. It is painful to the touch and about 1 1/2 inches long. It feels like it may be fluid filled. He did not suffer any trauma to that area. He has been getting daily headaches that are moderate to severe and aren't helped by medication. I am calling the dr today but he doesn't have a primary care so it may take some time to get him in.

Given all your husband's symptoms it is likely that your husband has an infection, likel due to a virus. Infections very commonly cause lymph nodes to swell. The location you are describing the lump in is one of the commonly affected lymph node chains.

Lymph nodes that are swollen to help fight infections commonly are tender and can feel fluid like although they typically are described as rubbery feeling.

While, by odds, this is the most likely explaination, there are some other possible causes.

It is possible that your husband does have a cystic structure that has subsequently caused an infection that may be the cause of the headaches, etc. These types of infections typically will require antibiotics to clear.

Since the symptoms have been going on for a few weeks I competely agree with him being seen by a doctor for a full examination.

Thank you so much for your reply. My husband ended up getting into the dr. He has pityriasis rosea and the lumps were lymph nodes. They put him on Allegra and wanted him to take a steroid, but he is going to just use the Allegra for now. Again thank you for taking the time to reply.
